Description

Technical Field

[0001] The utility model relates to the technical field of kitchen equipment, in particular to a waste heat recovery system for an induction cooker of a cooking robot. Background Art

[0002] In the trend of modern kitchens towards automation and intelligence, cooking robots have been widely used in the catering industry and household kitchens. Cooking robots have become one of the important kitchen cooking equipment to improve cooking efficiency and ensure the stability of dish quality. Existing cooking robots generally adopt a closed box structure, and an induction cooker for heating is arranged inside the box. When the cooking robot is working, the induction cooker will also generate a large amount of waste heat, and these waste heats will accumulate inside the box. If not removed in time, it is easy to cause the induction cooker to frequently give high-temperature alarms, affecting the working stability of the cooking robot. Through actual tests, it can be known that the temperature inside the box of the cooking robot can rise to 62 degrees after the induction cooker works for 1.5 hours, and the temperature at the air outlet can reach 75 degrees. Such a high temperature will also cause irreversible damage to other electronic components inside the cooking machine box, seriously affecting the normal service life of the entire cooking robot..

[0003] In the prior art, the induction cooker of the cooking robot is generally cooled only by air cooling, that is, only by accelerating the air flow near the induction cooker through a cooling fan, so as to accelerate the heat exchange with the air in the external environment. However, in this method, the heat is not effectively utilized, resulting in a waste of energy. The applicant found that another important device commonly found in the kitchen - a warming cabinet generally needs to rely on consuming electric energy to increase the water temperature and keep the water temperature within a specific range, so as to achieve the warming of the internal items (generally cooked dishes). Therefore, if the heat discharged by the cooking robot can be collected and applied to the warming of meals, it can not only solve the cooling problem of the induction cooker of the cooking machine, but also effectively reuse the waste heat, achieving a two-for-one effect and conforming to the environmental protection concept of energy conservation and emission reduction. Summary of the Utility Model

[0004] The purpose of the utility model is to overcome the above-mentioned deficiencies of the prior art and provide a waste heat recovery system for an induction cooker of a cooking robot, which can achieve good heat dissipation of the induction cooker and at the same time recycle and utilize the heat.

[0005] The technical solution of the present utility model is: a waste heat recovery system for an induction cooker of a cooking robot, including a heating mechanism, a heat exchange mechanism and a heat preservation mechanism. The heating mechanism includes a chassis, an induction cooker body, a heat dissipation plate and a heat dissipation fan; the induction cooker body, the heat dissipation plate and the heat dissipation fan are all arranged on the chassis; the heat exchange mechanism includes a heat exchanger, a pipeline and a circulation pump; the heat preservation mechanism includes a heat preservation box, an electric heating pipe and a temperature controller; water is stored in the heat preservation box; the electric heating pipe is used to heat the water; the pipeline includes a hot water inlet and a cold water outlet, and both the hot water inlet and the cold water outlet are arranged in the heat preservation box. Under the action of the circulation pump, the water in the heat preservation box flows from the cold water outlet to the heat exchanger, absorbs heat at the heat exchanger and then returns to the heat preservation box from the hot water inlet.

[0006] Further, the heat dissipation plate is arranged at the bottom of the chassis, the induction cooker body is arranged above the heat dissipation plate, ventilation holes are arranged on two opposite side walls of the chassis, and the heat dissipation fan is arranged on the side wall of the chassis. The heat dissipation fan is used to make air enter the chassis from the ventilation hole on one side wall of the chassis, and then flow out from the ventilation hole on the other side wall of the chassis after passing through the heat dissipation plate.

[0007] Further, the heat exchanger is arranged on the side where the air flows out of the chassis, so that the air flowing out of the chassis enters the heat exchanger for heat exchange.

[0008] Further, the heat exchanger is a coil heat exchanger.

[0009] Further, the hot water inlet and the cold water outlet are respectively arranged at both ends of the inner cavity of the heat preservation box. In this way, the hot water flowing out of the hot water inlet needs to be fully mixed and heat-exchanged in the heat preservation box before reaching the cold water outlet.

[0010] Further, a plurality of expansion interfaces are arranged on the pipeline. The expansion interfaces are used to be connected to devices that need heat. The devices that need heat include other insulation cabinets, water heaters, etc.; the expansion interfaces can also be used for networking of multiple induction cooker waste heat recovery systems.

[0011] Further, the temperature controller is connected to the electric heating pipe. When the temperature controller monitors that the temperature of the water in the heat preservation box is lower than the preset temperature range, it controls the electric heating pipe to work, and raises the temperature of the water in the heat preservation box to the preset temperature range through the electric heating pipe.

[0012] Further, the temperature controller, the induction cooker body and the circulation pump are all connected to the cooking robot controller and work together under the control of the cooking robot controller.

[0013] Advantages of the present utility model compared with the prior art: The present utility model solves the problem that the heat in the closed space caused by the induction cooker in the cooking robot box cannot be dissipated. At the same time, this heat can be reused, achieving the dual goals of energy conservation and emission reduction. Moreover, the entire heat exchange system has a low cost and is easy to promote. The pipeline has great expandability and can be connected to other devices that require heat, or can be networked to collect more heat. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] The following will further elaborate on the present utility model in conjunction with specific embodiments. The methods or functional components not specifically described in the embodiments are all prior arts; unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present invention belongs.

[0018] Embodiment 1

[0019] As Figure 1-2 shown, this embodiment is a waste heat recovery system for the induction cooker of a cooking robot, including a heating mechanism, a heat exchange mechanism, and a heat preservation mechanism. The heating mechanism includes a chassis 1, an induction cooker body (not shown in the figure), a heat dissipation plate 2, and a heat dissipation fan 3; the induction cooker body, the heat dissipation plate 2, and the heat dissipation fan 3 are all arranged on the chassis 1; the heat exchange mechanism includes a heat exchanger 4, a pipeline 5, and a circulation pump 6; the heat preservation mechanism includes an insulation box 7, an electric heating tube 8, and a temperature controller 9; water is stored in the insulation box 7; the electric heating tube 8 is used to heat the water; the pipeline 5 includes a hot water inlet 52 and a cold water outlet 51, and both the hot water inlet 52 and the cold water outlet 51 are arranged in the insulation box 7. Under the action of the circulation pump 6, the water in the insulation box 7 flows from the cold water outlet 51 to the heat exchanger 4, absorbs heat at the heat exchanger 4, and then returns to the insulation box 7 from the hot water inlet 52. The hot water inlet 52 and the cold water outlet 51 are respectively arranged at both ends of the inner cavity of the insulation cabinet, so that the hot water flowing out from the hot water inlet 52 needs to be fully mixed and heat-exchanged in the insulation box 7 before reaching the cold water outlet 51..

[0020] In this embodiment, the heat dissipation plate 2 is arranged at the bottom of the chassis 1, and the induction cooker body is arranged above the heat dissipation plate 2. Ventilation holes are arranged on two opposite side walls of the chassis 1. The heat dissipation fan 3 is arranged on one of the side walls of the chassis 1. The heat dissipation fan 3 is used to make air enter the chassis 1 from the ventilation hole on one side wall of the chassis 1, pass through the heat dissipation plate 2, and then flow out from the ventilation hole on the other side wall of the chassis 1. The heat exchanger 4 is arranged on the side where the air flows out of the chassis 1, so that all the air flowing out of the chassis 1 enters the heat exchanger 4 for heat exchange. In this embodiment, the heat exchanger 4 adopted is a coil heat exchanger.

[0021] In this embodiment, the thermostat 9 is connected to the electric heating tube 8, and the thermostat 9, the induction cooker body and the circulation pump 6 are all connected to the cooking robot controller, and can work together under the control of the cooking robot controller. When the induction cooker of the cooking robot does not work, the thermostat 9 monitors the temperature in the incubator 7 at any time. If the temperature of the water in the incubator 7 is lower than the preset temperature range, the thermostat 9 turns on the power supply of the electric heating tube 8, and the electric heating tube 8 starts to work until the temperature of the water in the incubator 7 is raised to the preset temperature range by the electric heating tube 8.

[0022] In some other embodiments, a plurality of expansion interfaces may be arranged on the pipeline 5. The expansion interfaces are used to be connected to devices that require heat. The devices that require heat include kitchen and bathroom devices such as a warming cabinet and a water heater.

[0023] The working principle of this embodiment: When the induction cooker of the cooking robot works, the heat dissipation fan 3 starts, sucks the ambient cold air into the chassis 1, and passes through the heat dissipation plate 2. After the cold air absorbs the heat of the heat dissipation plate 2, it becomes hot air (experimentally measured that the hot air can reach 75 degrees, meeting the condition of low-temperature recovery), and flows into the heat exchanger 4; the circulation pump 6 starts synchronously, pumps the low-temperature water in the warming cabinet from the cold water outlet 51 to the heat exchanger 4, and the low-temperature water exchanges heat with the hot air at the heat exchanger 4. After heat exchange, the low-temperature water can become high-temperature water (about 70 degrees), thereby taking away the heat of the surrounding environment of the induction cooker. Then the high-temperature water enters the incubator 7 from the hot water inlet 52, and mixes with the water in the incubator 7 for secondary heat exchange. After full mixing, it forms water with a lower temperature (about 50 degrees). Driven by the circulation pump 6, the mixed water with a lower temperature continues to flow to the heat exchanger 4 through the cold water outlet 51 for heat exchange (temperature increase), becomes high-temperature water and then returns to the incubator 7. In this way, circulation can achieve heat dissipation near the induction cooker and keep the temperature of the water in the warming cabinet within a specific range. When the cooking robot does not work, that is, when the induction cooker does not generate heat, the thermostat 9 monitors the temperature of the water in the incubator 7. If the water temperature is lower than the preset temperature range, the electric heating tube 8 is powered on, and the electric heating tube ⑧ raises the water temperature to the preset temperature.

[0024] The above are only some embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, the present utility model can have combinations and variations of the foregoing various technical features. Without departing from the spirit and scope of the present utility model, improvements, variations, equivalent substitutions made by those skilled in the art, or the application of the structure or method of the present utility model to other fields to achieve the same effect all fall within the protection scope of the present utility model.
